Fed's position shift triggers dollar selling, altcoins soar 6%

The Federal Reserve lowered interest rates by 25 basis points to 4.00%-4.25% on September 17, 2025, triggering a sharp rise in altcoins and driving the market size to a record $1.72 trillion. Weak employment data show that the unemployment rate is 4.3%, with 263,000 new unemployment benefits, which has led to aggravated Bitcoin's volatility, which has soared to $117,302.03. The regulatory clarity of the Market Structure Act and the $8.36 billion Ethereum-based real-world assets further enhance institutional investors' acceptance and market momentum.
